IMPROVEMENT IN POTATQ-DIGG-ER AND CULTIV'A'I'OR.

The Schedule referred to in them Letters Patent and making part of the lame.

To all whom it may concern:

Be it known that I, Moses JOHNSON, of Three Rivers, in the county of St. Joseph, and State of Michigan, have invented a new and valuable'Improrement in Potato-Diggels and Cultivators; and 'I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1, of the drawings, is a representation of my invention in. perspecti re.

Figure 2 is arem" 'vic\'v oitransverse bar and caster.

Figures 3, 4, 5, and 6, are details.

Myinvention has relation to potato-diggers and cultivatois; and

It consists mainly ina novel arrangement of devices, intended to serve as an eflicient digger or cultivator, at the will of the operator...

The letter A, of the drawings, represents the neap or beam of my apparatus, and

Letter B, the cross-bar, to which said beam is attached.

The letters 1) are handles,by which the machine is guided.

The letter H represents my plow or separator, a modification of which is shown in fig. 4.

The letters K are concave wheels, having hooks in their respective spokes or arms, represented by the letters a-.

These wheels are arranged in staples marked S, and are made adjustable therein by means of the screws 0, that some as axles, and the nuts'n operating thereon.

It will be obserred' that the .wheels K are arranged in the apparatus in positions diagonal to each other. I call these wheels the shakers, when used for digging potatoes.

The staples Sure respectively attached to the front side of the cross-bar B, by bolts, that pass through them and said bar, and which are held in place by suitable threads and nuts on the rear side of said beam.

Byv this arrangement, I am enabled to secure said staples in any desirable position, and thereby to adjust the shakers in the proper angle for the work required. v

The books a serve as aids in shaking the earth from the potato, and also as pul verizers of the soil.

The lct-teis 1: represent scrapers, arranged upon the staples, as shown, and which serve to scrape the earth from the shakers.

The letter Y .is ashield or rake, attached to the beam and extendiugrearward, as shown.

' This device is constructed'withteeth, that serve as a rake,mr"the ground, and aid in separating the earth from the potatoes, while at the same time, the solid body of the same, in conjunction with the teeth, serves to keep vines and other incnmbrances from the wheels.

I usually place one of these rakes on each side of the beam.

The letter P represents a caster, made adjustable 2, The shields Y, in combination with the wheels K and beam A.

3. The potato-digger herein described, having adjustable concave wheels K, plow H, staples S, shield Y, and caster I, constructed and arranged to operate substantially as specified.

In testimony that I claim the above, I have hereunto siibscrihed my name, in the presence of two wit nesses.

. MOSES JOHNSON.
